, v"My invention relates to improvements in vises and has for one objectto provide a new and improved form of vise which may be used for avariety of purposes and in a number When used without it may serve as adrill 5 of different situations.

VThe device may be used asa If it is desired to Y the mountable clamp maybe used and this clampwork-in position forvuse.

In practice the .threaded screw is raised out of engagement with thestationary half nut and the sliding member pushed forward until contactis established between the jaws of the vise and the objectheld thereinwhereupon the screw is returned within vthe half nut vand -a slightrotating movement of the screw exerts The inclined surfaces of lContact:of
